This invention relates to door holders of the type having a rotatable,and preferably yielding, floor engaging member or roller which isresiliently urged against the floor.

The aim of the present invention is to provide a door holder of thissort which is very practical in that it will effectively serve thedesired purposes.

A further aim of the invention is to rovide a door holder which ischaracterize by its simplicity in construction, its effectiveness inoperation, and its durability.

A further aim of the invention is to provide an improved door holderwith means of a practical, durable and effective nature for frictionallyholding the roller against free rotation and for automatically taking upwear of the parts.

Other objects will be in part obvious and in part pointed out more indetail hereinafter.

The invention accordingly consists in the features of construction,combination of elements and arrangement of parts which will beexemplified in the construction hereinafter set forth and the scope ofthe application of which will be indicated in the appended claims.y

In the accompanying drawing, wherein is shown one of the manyembodiments which the present invention may take:

Figure 1 is a side view of the holder with parts in section, the doorbein shown diagrammatically in edge view an a portion of the floor withwhich the roller is engaged being shown in section;

Fig. 2 is a front view of the door holder;

Fig. 3 is a transverse central sectional view through the roller;

Fig. 4 is a perspective view of one of the parts which are adapted tocarry the roller sections; and

Fig. 5 is a perspective view of one of the friction washers.

Referring to the drawing in detail, the

holder is shown as having a casing formed of a base plate 10 and a faceplate 11, the latter having a rectangular rib 12, which, together withthe base plate,'forms a hollow vertical barrel rectangular in crosssection. Obviously, the casing may be of any suitable shape, that shownin the drawing being illustrated by way of exemplification only. Ifdesired, the barrel may be of circular or other form and, instead ofstanding out from the door, as illustrated, it may be located within theplane of the door. The base plate has a slot 13 at the upper edge ofwhich is an outwardly extending.V finger or wall 14. The numeral 15designates a bolt corresponding in cross .section to and slidablyfitting within the barrel 12. The bolt may be in the form of a hollowtube provided with a bottom end wall 16. In order to hold the boltwithin the casing before the latter is attached to the door, there maybe fixed to the bolt a spring 17 having its upper end turned outwardlyso as to operate in the slot 13 and overhang the lower edge of thatslot. Positioned within the barrel and the bolt and between the walls 14and 16 is a spring 18 for resiliently holding the floor engaging rollerin engagement with the floor while permitting the roller to accommodateitself to any unevenness or irregularities in the floor as it passesthereover. The lower end of the bolt is provided with a pair ofdepending arms 20 provide-d with vertical slots 21 which extend to thelower ends of the arms. The numeral 22 designates a pin or bearingmember lon which the floor engaging element is rotatably mounted. Thispin has its ends tting in the slots 21 and, in order to prevent the pinfrom rotating, it has flattened faces 23, the diametrical distancebetween which is substantially equal to the width of the slots 21.

In accordance with'the present invention, the roller has a floorengaging member preferably of yielding material, such as rubber. In thepresent illustrative disclosure, the tloor engaging member is shown asbeing formed of two complementary ring-like parts 24, 24 positioned sideby side, but it is within the spirit of some of the appended claims tonave a. floor engaging member of one part or more than two as desired.The oor engaging member, comprising the parts 24, 24, is carried by ametal core which, in the presentinstance, is in the form of twocomplementary partsor hubs 25, 25 preferably of like construction andpositioned in reverse relation to oneI another. llach of the hubs 25 hasa cyliiulriral portion 26 adapted to tit closely within the opening ofthe respective roller part 21 and a head or flange 2T adapted to engageagainst the side face of the respective roller part 24. 'lhe inner endsof the hubs 25, 25 are counterbored to provide a recess or chamber for aspring 29 which constitutes means for urging the parts 25, 25 outwardlyand against cooperating fixed frictional elements. In the presentillustrative disclosure, these fixed frictional elements are in the formof disks or washers 30 which are positioned between the arms 2O of thebolt and the ends of the core of the roller. In order to prevent thesedisks from rotating, they may be provided with bent-out lugs 31 whichextend into the slots 21 of the arms 20. The core parts 25, 25constitute frictional elements rotatable with the floor engaging memberor the parts thereof. rlhe peripheries of the cylindrical portions 26 ofthe core parts may be corrugated, as shown in Fig. 4, in order toprevent slippage between the roller parts 24 and the core parts.Obviously, the construetion of the core of the roller may be varied inaccordance with the different constructions of floor engaging memberswhich may be employed. In Figs. 1 and 2, I have shown on the outside ofeach arm 2O a disk 35 having a slot 36 corresponding to the slots 21 andadapted to receive the flattened portions 23 of the pin 22.

The operation of my improved door holder will be readily understood fromthe foregoing description taken in connection with the accompanyingdrawing. The door holder is secured to a door adjacent the lower freeedge thereof, as shown in F ig. 1, the door being diagrammatically shownand being designated by the letter D. The spring 18 resiliently forcesthe bolt 15 downwardly so as to press the floor engaging member orroller against the floor which is designated by the lettenF. The rollerwill flatten out somewhat, as illustrated in Fig. 1, the extent offlattening depending upon the resiliency or softness of the roller andthe pressure of the spring 18. Due to the force with Which the roller isurged against the floor, and to friction between the elements 25 and 30,the roller is held against free rotation, and thus the holder willmaintain the door in any position of adjustment. However, as the rollermay, when sufficient force is applied to the door, turn upon itsbearing, the door may be moved when one gives it a push or shove inhurrying through the doorway As the floor engaging member rolls over thefloor, it does not mark, scratch, or otherwise disfigure the floorsurface. Since the floor engaging roller is resiliently urged againstthe floor, it may move up and down in accordance with irregularities inthe floor.

It will further be observed that with my improved arrangement, theroller is frictionally held against free rotation due to the engagementbetween the cooperating pairs of frictional elements 25 and 30, thefrictional elements 25 being caused to rotate with the roller, and thefrictional elements 3() being fixed, and further the frictional elements25 being urged by the spring 29 against the frictional elements 30. Dueto this arrangement, wear between the frictional surfaces isautomatically taken up so that the holder will have a long and effectivelife Without the necessity of repairs. Owing to the floor engagingmember being in two parts 24, 24, these parts may have a differentialrotary movement as they roll over the floor, a feature which may be ofadvantage as the door swings in an are.

My improved arrangement is very simple in construction, may beeconomically made, and has a neat and pleasing appearance.'

As many changes could be made in the above construction and manyapparently widely different embodiments of this invention could be madewithout departing from the scope thereof, it is intended that all mattercontained in the above description or shown in the accompanying drawinshall be interpreted as illustrative and not 1n a limiting sense.

It is also to be understood that the language used in the followingclaims is intended to cover all of the generic and specific features ofthe invention herein described and all statements of the scope of theinvention which, as a matter of language, might be said to falltherebetween.
